Product Description
Microchip AT27C256R-45JU is an EPROM (Erasable Programmable Read-Only Memory) chip providing 256 kB of permanent, non-volatile storage in a 32-pin PLCC package. This OTP (One-Time Programmable) device is designed for through-hole mounting, offering stable mechanical installation and reliable electrical connections.
The memory is organized as 32K words with 8 bits per word, accessed via a parallel interface, with a maximum random access time of 45 ns, enabling fast data retrieval suitable for embedded system applications. Operating voltage ranges from 4.5V minimum to 5.5V maximum ensures compatibility with industry-standard digital voltage supplies.
Operating temperature range from -40°C to 85°C provides suitability for industrial environments. The device has a compact physical footprint of 11.5 mm length, 14.3 mm width, and a height of 3.37 mm, facilitating integration in space-constrained PCB layouts.
The EPROM is OTP, meaning it can be programmed once and does not support reprogramming or ultraviolet erasure. It draws a low supply current of 100 µA, making it efficient for low-power electronic devices. This product does not conform to any specific automotive standards and is intended for general semiconductor memory applications.
This EPROM is ideal for data retention in embedded systems within industrial, electronics manufacturing, and repair applications. The PLCC package provides durability and ease of use in through-hole PCB assembly processes.
Suitable for applications requiring reliable permanent memory storage without reprogramming needs. Compact size and low power consumption make it ideal for diverse electronic designs, including prototyping and small-scale production.
Designed to meet general electronic component standards with no additional certifications. Explore more Memory Chips and semiconductor products suitable for your industrial and electronic component needs at EnvMart, your trusted technical product source.
